Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Perth Observatory says it has received reports of lights dancing in the sky across a significant part of WA's Midwest and Goldfields, with an explanation yet to be found.

Air is invisible, but its movement shapes everything around us. Using light refraction, heat, and fluid dynamics, scientists have developed ways to see the flow of air in real time, revealing how it ...
